worked perfectly

This tool works perfectly on Gibson style headstock truss rod nuts. Slipped right in place and the lever arm was the perfect angle. Long enough to apply leverage, but not so long as to make it easy to snap the truss rod, or strip the threads.

Does what it’s supposed to do...

and fits in that tight spot where a ratchet and other wrenches are too big. I would it find it a more convenient tool if it had a small Phillips head screwdriver at the end of the handle for removing the truss rod nut cover.

Rickenbacker Truss Rod Problem Not Solved

Unfortunately this well made product did not fit under my new Rickenbacker 12 string truss rod nut because the truss rod cavity is simply to shallow. This is a problem which Ric is well aware of and appears to dismiss by advising the owners should grind down the nut drivers. Either way the guys at Stew Mac were really nice and helpful but it is not there fault. I will get a grinder I guess.

Did exactly what I needed it to do

I bought this cause I was fixing a friend's 1981 Gibson Les Paul and the trussrod end was a 5/16 nut end and I had to order this tool cause the bullet shape fit into the trussrod slot nicely and got the job job and the guitar plays great!
